feat: make multiselect menu more discoverable

[GretaD]

fixes #10231

hovered

selected

To clarify

• Should the checkmark be shown when the whole message is hovered, or when the avatar is hovered. Right now, the check mark is shown when the avatar is hovered.

• If all selected messages are read, there is a bulk Mark us unread. If at least one message is unread there is only a bulk Mark as read and no more Mark as unread.
• There is no option to un-flag (un-star) a message (was not there before either)
• Before it was possible to clear the selection. This feature is gone.
• The expansion of the multiselect buttons makes the list move and at least on Firefox it's a bit jittery.
• The hover state of the avatar of a selected message is identical to a message that is not selected. This means you get no click feedback when selecting a message until you leave the element again.

Same scenario as favorite, unfavorite, explained below

It is there, i added it, but its one button that replaces each other. I just changed the icon for both states.

You mean unselect, right? Its the second icon before last.

I'll test it there and fix it.

Yes, you need to select the avatar to actually select it. Selecting the message will open the message and should not select it( ✔️ as an action). These 2 actions should be split, you shouldnt select ✔️ a message when you only want to open it. So, i would say the hover state of the avatar should be the same, regardless of the state of the message, but, i can change it if you have an idea how.

I havent changed anything from the logic that was there. The behavior is the same as the original menu actions, i only added new icons. So, you propose to have both buttons out like in the mark as important example? When you have both actions selected, like for example, one favorite, and one not favorite, to show both icons, favorite and unfavorite?
In general, you dont expect people to do that.

Indeed.

1. Click the avatar to select a message
2. Stay hovering

expected: dark checkmark
actual: light checkmark

Yes. For Mark important/unimportant we also have both options

Tested. Looks and works great. Much better visually, I think.
